AIR-GUN.

SPECIFICATION forming part f Letters Patent NO. 455,942, dated July 14,1891.

Application filed February 9, 1891. Serial No. 380,856. (No model.)

To @ZZ whom it may concern.-

Beit known that I, CLARENCE J. HAMIL- TON, a citizen of the UnitedStates, residing at Plymouth, in the county of Vayne and State ofMichigan, have invented certain new and useful Improvements in Air-Guns;and I do declare the following to be a full, clear, and exactdescription of theinvention, such as will enable others skilled in theart to which it appertains to make and use the same, reference beinghadto the accompanying drawings, and to the letters of reference markedthereon, which form a part of this specification.

This invention relates tol new and useful improvements in air-guns; andit consists in a certain construction and arrangement of parts, ashereinafter fully set forth, the essential features of which beingpointed out particularly in the claims.

In the accompanying drawings, forming a part of the speciication, Figurel is a side elevation of an air-gun embodying my improved features,showing by dotted lines the v stock broken down, as when compressing thespring. Fig. 2 is an enlarged plan view of the stock and breech, saidparts being in the position shown by dotted lines in Fig. l,

la portion of the rear end of the breech or false barrel being brokenaway to show the construction of parts. Fig. 3 is an enlargedperspective view of the stock, trigger-guard, and bed-plate detachedfrom the barrel, one of the stock-plates being removed. Fig. 4 is across-section through t-he stock-plates on dotted line of Fig. '8.

Referring to the letters of reference, A inv dicates the stock skeletonor frame, which is extending from the wall of said sockets that engagein corresponding indentures formed in the ends of said-stock, whichindentures are not shown.

C indicates the bed-plate for the false barrel H, and which also forms ahousing for the trigger d, said plate being secured to said barrel bysoldering.

D indicates a bracket or dividing-plate formed integral with thetrigger-guard D',

and which is secured to the bed-plate C in any desired manner. The rearend of said plate D lies between the stock-plates B, and

is provided with trunnions c, that have bearl lugs i, that engage in therecesses fr in each side of the plate D and lock the stock when in theposition shown in Figs. l and 3. f

F indicates a connecting-link, the rear ends of which are bent at rightangles and pivotally secured in the adjacent inner faces of' the endportions E of the plates B, as shown at s in Fig. 2, the opposite end ofsaid link being coupled to the hook 71J in the rear end of the rod G,that carries the piston, and which compresses the spring when actuatedby the link F, said piston and spring (not shown) being located in thecylinder or false barrel H, to which is connected the true barrel I,which construction is such as is in common use. The spring of the gun iscompressed by breaking down the stock, the plates B of which beingpivoted or fulcru med on the trunnions c, the ends E thereof, to whichthe link F is attached, are thereby thrown rearward, drawing. the rod' Gand compressing the spring, which position of parts is shown in Fig. 2and by dotted lines in Fig. l. A detent actuated by the trigger engagesthe hook h of the rod G when drawn back and holds the spring compressed.The stock is then returned to the position shown in Fig. l, when the gunis ready to be discharged, which is accomplished by pulling upon thetrigger in the ordinary manner.

As the stock is thrown down in compressing the spring, the lugs e' onthe inner faces of the plates B ride out of' the depressions u TOO inthe plate D and over the raised portion t thereof, springing said platesslightly apart, as shown in Fig. 4, the metal of which said plates areformed being sufficiently resilient to permit them to spring freelyapart when the lugs are riding out ofv the depressions and to closetogether again when the stock is returned to the position shown in Fig.1, so that the lugs t' will re-engage in the depressions o and lock thestock in said position.

Having thus fully set forth my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. In an air-gun, the following conjoined elements: the bed-plate andbracket having trunnions thereon, and the stock-plates journaled on saidtrunnions and carrying the stock-skeleton, substantially as specified.

2. In an air-gun, and in conjunction, the bed-plate, the bracketattached thereto, the stock-plates, said stock-plates having a pivotalconnection on the bracket, the link attached to said plates at one endand adapted to be coupled at its opposite end to the compression-rod,and the screw or rivet binding the stock-plates together.

3. In combination with the bed-plate, the bracket having thetrigger-guard formed integral therewith, the metal stock-plates, saidstock-plates being journaled on the bracket, and the link attached tosaid plates at one end and adapted to be coupled at its opposite end tothe compression rod, the stock-skeleton being secured to the metalstock-plates.

4. T he combination, with the bed-plate having the bracket andtrigger-guard attached thereto, said bracket having a recess in one ofits faces, of the stock-plates journaled on said bracket and having alug to engage with the recess in the bracket, the link attached to saidplates at one end and adapted to be coupled at its opposite end to thecompression-rod, and the screw passing through the rear ends of thestock-plates.

5. In combination with the bed-plate, the bracket, the stock-platesjournaled on the bracket and having means of locking to and unlockingfrom said bracket as the stockplates are actuated, substantiallyspecified.

6. In an air-gun, the false barrel, combined with the bed-plate having arearwardly-extending bracket, the stock-plates pivoted on said bracketand having a stock-frame attached to the rear ends thereof, thespringcompression rod, and link coupling said rod to the stock-plates.

7. In combination with the bed-plate, the bracket having the trunnionsand triggerguard` formed integral therewith, the twopart stock mountedon said trunnions, the link attached to said stock at one end andadapted to be attached at its opposite end to the compression-rod, andmeans for holding said stock on said trunnions, substantially asspecified.

Y In testimony whereof Iaflix my signature in presence of two witnesses.

CLARENCE J. HAMILTON.
